The value proposition of hybrid PV systems extends well beyond simple capacity addition. By pairing complementary technologies, these systems deliver enhanced energy security through more stable and reliable power supply. Storage components enable surplus solar energy to be deployed during peak demand or low-generation periods, while wind integration provides natural generation balance, often producing when solar output is minimal.
For grid operators and energy consumers alike, this translates to increased system flexibility, improved asset cost-effectiveness, and significantly greater reliability - ultimately reducing dependence on fossil fuel backup generation.
Despite these advantages, Europe has barely scratched the surface of hybrid deployment potential, according to SolarPower Europe, the premier association for the European solar PV sector that unites over 300 organisations. Since 2015, solar+storage configurations have represented just 5% of total battery additions across Europe, with deployment heavily concentrated in the UK (62% of total PV+BESS capacity). The UK's success stems from supportive policies including the Capacity Market and Contract-for-Difference schemes, streamlined permitting, and market reforms facilitating battery participation.
Meanwhile, EU member states remain significantly behind, with Sweden (10%), Italy (8%), Germany (6%), and others showing modest deployment levels. The PV+wind segment shows even less progress, with only 555 MW installed continent-wide by the end of 2024 - less than 1% of the utility-scale solar fleet - though Poland has established early leadership with 277 MW.
The limited uptake of hybrid configurations largely stems from regulatory frameworks that haven't kept pace with technological evolution. The authors of the study identified current bottlenecks that include:
Grid connection procedures that fail to prioritize or facilitate hybridization
Permitting processes that treat hybrid components separately rather than as integrated systems
Support schemes not designed to capture the full value of hybrid configurations
Grid tariffs that often double-charge storage components
Inadequate certification frameworks for renewable generation flowing through storage
For energy industry stakeholders, the message is clear: with proper regulatory reform, hybrid PV systems could play a pivotal role in accelerating Europe's clean energy transition. Success stories from markets like the UK demonstrate that where policy frameworks evolve to recognize the distinct attributes of hybrid systems, deployment follows.
The European Commission's anticipated Flexibility Package and Energy Storage Action Plan represent critical opportunities to address these barriers at scale. Meanwhile, best practices from frontrunners like Denmark (grid hosting capacity maps), Spain and Austria (flexible grid connection agreements), and Portugal (streamlined electrical licensing) offer immediate pathways for improvement that other member states can adopt.
As Europe strives to enhance energy security, reduce system costs, and accelerate decarbonization, unlocking the full potential of hybrid PV systems must become a cornerstone of our integrated energy strategy, the report states.
